The VPN authentication functionality in Cisco Adaptive Security Appliance (ASA) Software allows remote attackers to cause a denial of service (device reload) by sending many username-from-cert IKE requests, aka Bug ID CSCua91108.
Does this matter?
Lower severity and a low EPSS score (1.70%). Track it; it rarely justifies an emergency change on its own.
